    Description

      Today we performed a test shot on our smaller Cray Aries cluster (700 nodes) with a non-patched lustre 2.8 GA client specially build for this system. The test were run against our atlas file system which is running a RHEL6.7 distro with the lustre version 2.5.5 with patches. During our test shot while running an IOR single shared file test across all nodes with the stripe count of 1008 the MDS server ran out of memory. I attached the dmesg output to this ticket.
